About how long does it take to charge fully using the hand crank? Has anyone owned this long enough to experience memory loss with the rechargable pack?

Fully charge... Havn't done that yet. Owned it for many years now. It stays in my trailer all year and gets used each time we camp. The rechargable pack still works, but I only use it for a minute or two just to get a quick light when needed.

I charged it for 12 hrs and it was fully charged. after that initial charge it depends on how long I use it. I do not charge it after every use because I have always read that is not good for rechargeables. and I do not leave it plugged in either.

I've left mine charging for several days, and have never had performance issues with the battery. I know that's purely anecdotal, but its not something I've ever had an issue with.

I use this flashlight often,maybe 10 minutes at a time. I do not recharge it very often. I have bought several rechargeable crank flashlight and this one is my favorite for size and convenience.

I use my Black and Decker almost every single day in my motorhome. I simply leave it plugged in, in an inconspicuous location i between uses. I have no idea how long it would take to charge if the battery completely ran down; I've never had that happen. I tend to use it in 5-10-minute spurts and it's been fantastic. Hope this helps.

It's a matter of personal preference. I use it mostly with my IPhone. I'm able to quickly recharge my phone battery without having to search for a plug. It's a quick charge; only takes about 15-20 minutes from a 40% battery level status. Also my recharge can occur while I'm on the move. The charging unit is good for multiple (4-5) charges without having to plug in for recharge. Only thing is the unit is a little bulky & heavy I'm still able to fit in my bag. Hope this helps you to decide.

According to the manual, "Charge time depends on cranking rate and duration. For example turning the crank at about 2 turns per second for 90 seconds should power the radio for about 10 minutes." The battery pack is 3.6V, 300mAH. It would probably take about 5 minutes of cranking to fully charge it, longer than most people would be willing to do continuously.

I have not run the battery down before recharging. I will plug it in about every 2 weeks just to keep it charged and I use the keyboard often. I have been impressed with how long the battery does last and have never had a problem with this device.

I have only had it a short time but if it gets a full 7 hour initial charge then run it down, which takes about 15 to 20 minutes, then re charge mine runs at least 30 minutes now and should go longer as the recharge process is repeated. I hope this was helpful

Well I have played it straight for about four hours without having to recharge it. I haven't drain the battery completely yet. I have also used it after in not being charged after two weeks. The battery last a long time in other words.

Not long, I have had the toothbrush several months now and I have gone well over a week without charging it. I can't say exactly how long, but if I let it die and put it on charge before sleep, it can fully charge by the time I wake up

That sounds about right. It should last at least 7 days, fully charged. Btw, I use OralB in the .orning and Pursonic at night. I bought my OralB from Walmart and within a week or so the handle stopped charging. I called.OralB and there was a recall for the nadle due to bad batteries. They sent me a handle from Germany, best handle I've ever had. Going on 4years of service.

Not sure how much time you'd be spending actively using it vs just having it ready to be used, but I am charging it every other day. I do find that it seems to take longer than other devices to re charge fully. And the cord is oddly short! I received a pop up Msg that encouraged me to close unused apps to preserve battery life. By long pressing the center button open apps appear and they swipe away to close.

It takes mine 8 to 10 hours for a complete recharge. I dont leave it on charge all the time. My last Battery lasted three years good for a lead acid battery.

I just plugged in my cell phone into the USB port and it did not seem to charge the phone from the installed AA batteries. There may be a setting I don't have set right for using the batteries. When I used the crank, it did start charging the cell phone. I didn't do it for long so I'm not sure how long it would take to fully charge a dead cell phone. I would think a camcorder would take a lot more juice. Good arm exercise though...

I don't know how you are using the charger. I've had mine since May. I only use it rarely when I am traveling and need the extra boost. If you been charging and discharging the battery daily, you might have created a memory effect in the battery. Lithium battery were not supposed to have the memory effect problem, but it has been found that is not completely true. I would contact Amazon/Jackery to see if they would replace the battery since it's been only a few weeks.

So far I have listened to music solid for about a two hour drive one way and then again for 2 hours back. The battery life didn't seem to decrease at all. Maybe went down 20-30%.I have so far gone a few days straight without charging and taking small trips each day listening to music the whole time. It's definitely good enough to use for a day and not charge and still have enough juice for another ride or two. My buddy wore his battery out after maybe 4-5 days of not charging. Definitely good enough given you're usually home in time to recharge. This model supports charging while using it on your bike. I got a battery hookup USB charger but honestly haven't even had to use that yet. So far I have listened to music solid for about a two hour drive one way and then again for 2 hours back.
